Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

This paper investigates the interaction of energetic solar protons measured by the Geostationary Operational Environmental Satellites (GOES), with the aluminum shielding structure of different thicknesses and calculates the dose distribution inside an tissue equivalent phantom inside the aluminum structure. In addition to the incident energetic protons, the major contributors to the total dose inside the phantom are the secondary protons and neutrons generated by spallation reactions in the aluminum structure and the phantom. Three modes of incidence of source protons are considered: center seeking, planar, and isotropic. The center seeking mode is the most conservative, resulting in the highest dose values and distribution inside the phantom, compared to those at the phantom's outer surface. Both the planar and isotropic modes result in much lower dose values that are more evenly distributed throughout the phantom.
